Elastic and thermoelastic properties of twelve adducts of betaine, (CH3)3NCH2COO, with H2O, HCl, HBr, HI, HNO3, H2SO4, H3PO3, H3PO4, 1,4-toluene sulfonic acid, MnCl2 and KBr
Abstract
Large single crystals of optical quality of the following betaine adducts have been grown from aqueous solutions (b = betaine): b · H2O, b · HCl, b · HBr, b · HI, b · HNO3, b · H2SO4 · H2O, b2 · H2SO4, b · H3PO3, b · H3PO4, b · 1,4-CH3(C6H4)SO3H, b3 · 2MnCl2, b · KBr · 2H2O. The crystals were characterized by their metric data, space group symmetry, density and thermal expansion. Complete elastic and thermoelastic tensors were determined by the aid of ultrasonic resonance methods. All betaine adducts investigated so far display common structural features and similar physical properties expressing the dominant role of the betaine molecule in the crystalline bond system. In addition to the already known phase transitions a ferroelastic phase transition in b · 1,4-toluene sulfonic acid at about 140 K, which is accompanied by a softening of c66, and a first-order transition in b · KBr · 2H2O at about 335 K were observed.
